On Saturday, 27th of June, 1868, I took a botanical trip to Selkirk 
with some of my pupils, and while walking along the sandy banks of 
the Ettrick, between Selkirk and Philiphaugh, a Mieracium was 
gathered by my zealous pupil Mr. Mawson, which at once attracted 
my notice. It was quite distinct from any of the British Mieracia, 
and it was obviously growing in a wild station. Although, on account 
of the hot weather of last summer, many of the specimens were in a 
shrivelled state, still a sufficient number remained in a condition fit 
for examination. I determined it to be Hieracium collinum, of Fries. 
I subsequently sent a specimen to Professor Babington, who agreed 
with me as to the species. 
The following are the characters of the plant :—Hieracium collinum, 
Fries, Symbole ad Hist. Hieraciorum, p. 29; viride (raro glau- 
cescens); caule inferne paucifolio apice cymoso-corymboso furcatove ;

It occurs in Northern Europe, and after H. Pilosella, Liun., and H. 
Auricula, Linn., it is the most common species in dry mountains 
throughout the middle and north of Sweden, as far as Lapland, and 
also in the interior of Norway up to Finmark. It is rare in the moun- 
tains of Germany. It flowers in June. 
The root is descending, oblique, and premorse, usually giving off 
stolons. The stem is hollow, straight, with 1-3 leaves, reddish, with
